Biomass gasification gas purification system and method, and methanol production system and method

摘要

A biomass gasification gas purification system has a dust removal apparatus for filtering soot and dust from biomass gasification gas (including tar component) obtained through the gasification of the biomass using a biomass gasification furnace, a desulfurization apparatus for removing sulfur oxide component in the filtered biomass gasification gas, first to third pre-reformation reactors that provide pre-reforming catalyst for reforming the tar component in the biomass gasification gas after desulfurization, and first and second coolers that are interposed between the first to third pre-reformation reactors, and for cooling the reformed gas.

主权项

1. A biomass gasification gas purification method comprising:
filtering soot and dust from biomass gasification gas obtained through the gasification of the biomass using a biomass gasification furnace; removing sulfur oxide component in the filtered biomass gasification gas; extracting a part of the biomass gasification gas after desulfurization; reforming the tar component in the biomass gasification gas after desulfurization using at least two or more pre-reforming reactors; cooling the part of the biomass gasification gas by using a cooler; and supplying the cooled biomass gasification gas between the pre-reformation reactors respectively.
